Llinares and colleagues studied how classroom wall color hue influences student performance. They determined via a virtual reality project that “Cold hues improve attention and memory performance. . . . The objective of the present study is to analyse the impact that warm and cold hue coloured classroom walls have on the cognitive attention and memory functions of university students. . . . performance was quantified through psychological (attention and memory tasks) and neurophysiological (heart rate variability and electroencephalogram) metrics related to the cognitive functions analysed.”
